The main conceit here is sentient stars - that’s right - giant balls of fusing gas that can think and use pseudopods of plasma to manipulate objects. In this, the third book of the Starchild trilogy, we learn that Cliff Hawk and a Reefer have allowed their rampant curiosity enough rope that they have created an artificial intelligence of plasma - a rogue star. Uninhibited by any moral code however, the rogue grows by absorbing any matter and energy around it, even if it is other objects that can think, like humans. Having killed and absorbed Cliff Hawk the rogue exhibits some of Hawk’s traits, like his love for the female human Molly Zaldivar, which makes the nascent star’s thought processes unstable, to say the least. Sallying forth into the fray is the doting figure of unrequited love, Andreas Quamodian, who tries desperately to save Molly from the clutches of the rogue star, which now feels threatened by the combined intellect of thirteen stars known as Almalik. On a crash course with Almalik the rogue star must learn some form of restraint or both it and Almalik will be destroyed. Jack Williamson & Frederik Pohl have penned a page-turner which unfortunately is very hard to suspend disbelief about.
